2.测试代码
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <hiredis/hiredis.h>int main()
{// 创建Redis连接redisContext *c = redisConnect("192.168.127.128", 6379);if (c == NULL) {// 如果无法分配redis上下文，直接报错并退出printf("Can't allocate redis context\n");return 1;} else if (c->err) {// 如果连接有错误，打印错误信息并释放上下文，然后退出printf("Error: %s\n", c->errstr);redisFree(c);return 1;} else {// 连接成功时打印消息printf("Successfully connected to Redis server\n");}// 切换到数据库6redisReply *reply;reply = redisCommand(c, "SELECT 6");if (reply == NULL) {printf("Error executing SELECT command\n");redisFree(c);return 1;} else if (reply->type == REDIS_REPLY_ERROR) {printf("Error reply: %s\n", reply->str);freeReplyObject(reply);redisFree(c);return 1;}freeReplyObject(reply);// 插入一些数据，例如插入一个键值对 "name": "John"reply = redisCommand(c, "SET name John");if (reply == NULL) {printf("Error executing SET command\n");redisFree(c);return 1;} else if (reply->type == REDIS_REPLY_ERROR) {printf("Error reply: %s\n", reply->str);freeReplyObject(reply);redisFree(c);return 1;}freeReplyObject(reply);// 可以继续插入更多数据reply = redisCommand(c, "SET age 30");if (reply == NULL) {printf("Error executing SET command\n");redisFree(c);return 1;} else if (reply->type == REDIS_REPLY_ERROR) {printf("Error reply: %s\n", reply->str);freeReplyObject(reply);redisFree(c);return 1;}freeReplyObject(reply);redisFree(c);return 0;
}
